Beginners Guide to Thickeners - Outotec

Many thickener installations operate with water recovery below design limits largely through conservative control and low prioritization of thickener optimization. The operation of the thickener must accommodate fluctuations – control for disturbances – in the process feed stream to deliver a clear overflow and thickened underflow.

CHAPTER 5: SLUDGE TREATMENT FACILITIES 5.1

Floatation thickeners are equipped with both surface skimmers and floor rakes. The surface skimmers remove floating material from the thickening tank to maintain a constant average float blanket depth. Floor rakes are essential for removing the non-floatable heavier solids that settle to the bottom of the floatation thickener.

CHAPTER 3 SLUDGE THICKENING - Marmara Üniversitesi

The gas formed will cause the flotation of the solids in the thickener. Chemicals like chlorine (CI 2) need to be added to inhibit the biological activity. A well operated thickener will have a solids recovery of about 95% [3]. Design of Thickeners The thickening process takes place in a settling tank with long-enough solids retention time.
